About this study
Official title: Impact of Ophthalmic Surgeon Experience on Early Postoperative Central Corneal Thickness After Cataract Surgery
To assess the impact of surgeon experience on early postoperative central corneal thickness (CCT) in eyes that have undergone phacoemulsification-based cataract surgery.
Read the detailed description
Cataract surgery is the most commonly performed surgical procedure. Although phacoemulsification is considered a safe method of performing cataract surgery, the risk of endothelial cell loss (ECL) remains.
Given that the surgical technique and speed typically improve with surgeon skill and experience, the purpose of this study was to evaluate the impact of surgeon experience on the occurrence of ECL, as reflected by the presence of corneal edema.

What is being measured
The primary outcome is the main question the study is designed to answer.
Early postoperative corneal edema
Calculated in micrometers, using pachymetric measurements to estimate central corneal thickness

Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Early postoperative corneal edema (time frame: hour 2). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2018; AzTrials last refreshed its copy on 8 Nov 2026.
